Description

自供能式主被动复合转动惯量驱动控制***Self-powered active and passive composite moment of inertia drive control system 技术领域Technical field
本发明涉及***中振动的抑制领域,具体而言,涉及一种自供能式主被动复合转动惯量驱动控制***。The invention relates to the field of vibration suppression in a system, and in particular to a self-powered active and passive composite moment of inertia drive control system.
背景技术Background technique
振动是生活中常见的一种现象,工程设施、结构在使用过程中往往会由于外部荷载的作用产生振动,严重的产生摇摆,甚至破坏。为了解决由结构物振动引起的各种问题,振动控制技术应运而生。Vibration is a common phenomenon in life. Engineering facilities and structures will often vibrate due to external loads during use, causing severe sway or even damage. In order to solve various problems caused by the vibration of the structure, vibration control technology came into being.
结构振动控制技术主要分为以下四个方面:主动控制、被动控制、半主动控制以及混合控制。对于各种工程结构,恰当地安全振动控制***能够有效地减轻结构的动力响应,减轻结构的破坏或者疲劳损伤。Structural vibration control technology is mainly divided into the following four aspects: active control, passive control, semi-active control and hybrid control. For various engineering structures, proper safety vibration control system can effectively reduce the dynamic response of the structure and reduce the damage or fatigue damage of the structure.
结构的运动通常由平动以及扭转摆动组合而成。研究表明由于平动调谐质量阻尼器(英文名Tuned Mass Damper,TMD)、主动质量阻尼器/主动扭矩输出装置(英文名Active Mass Damper/Driver,AMD)在扭转摆动中由于需要提供向心力导致控制效果大大减弱甚至完全失去作用,对回转摆振控制几乎无效。然而具有回转摆振运动特性的结构运动形式极为常见,如:悬吊结构(吊钩、吊车等)的摆动;不规则建筑在风荷载作用下的扭转摆振;海洋平台在海浪、风、冰等耦合作用下的扭转摆振等;宇宙飞船、空间结构在运行过程中,由于自身姿势调整以及太阳能帆板打开引起的扭转摆振运动;高速铁路机车,由于微小激励引起的车身的扭转摆振运动等。因此需要一种特殊的控制***,使其可以自动克服(或摆脱)重力场对控制***自身的影响(离心力作用),或者使控制***自身的工作/运动规律与重力场解耦,***自振不受重力影响,从而发挥控制***有效控制作用。The movement of the structure is usually a combination of translation and torsion swing. Studies have shown that due to translational tuned mass damper (English name Tuned Mass Damper, TMD), active mass damper/active torque output device (English name Active Mass Damper/Driver, AMD) in torsional swing, the need to provide centripetal force leads to control effects It is greatly weakened or even completely lost, and it is almost ineffective in controlling the swing vibration. However, structural motion forms with slewing vibration characteristics are extremely common, such as: the swing of suspended structures (hooks, cranes, etc.); the torsional shimmy of irregular buildings under wind loads; offshore platforms in waves, wind, and ice Torsional shimmy under the coupling action of the same; spacecraft and space structure during operation, the torsional shimmy motion caused by the adjustment of their own posture and the opening of solar panels; high-speed railway locomotive, the torsional shimmy of the body caused by small excitation Sports etc. Therefore, a special control system is needed that can automatically overcome (or get rid of) the influence of the gravity field on the control system itself (centrifugal force), or decouple the work/motion law of the control system itself from the gravity field, and the system can vibrate naturally It is not affected by gravity, thus exerting the effective control function of the control system.
主动控制技术因其具备控制效果好、鲁棒性好等优点,近年来发展迅速。但是,在技术的研究和实践过程中,人们发现由于主动控制装置需要外部能源来驱动工作,在工程结构遭到破坏时,能源的供应被意外切断会导致主动控制装置的完全失效。Active control technology has developed rapidly in recent years because of its good control effect and robustness. However, in the process of technical research and practice, people found that because the active control device needs external energy to drive the work, when the engineering structure is damaged, the accidental cut off of the energy supply will cause the active control device to completely fail.
综上,结构振动控制***具有不可或缺的作用,但是现有的结构振动控制***具有以下几方面的不足:第一,平动TMD控制装置只能控制结构的平动运动而对回转摆振控制无效,平动AMD控制装置虽然可以控制回转摆振,但是控制效率极低,无法满足使用要求;第二,被动转动惯量调谐阻尼器对回转摆振运动控制有效,但是其需要针对结构自身进行复杂的调频,对某些复杂结构控制效率较低,效果不佳,存在鲁棒性低,可控性低,适用范围小等缺点;第三,控制***适用范围小,控制力输出有限,控制效果有限,且控制***能源利用率无法保证,无法满足经济性的需求;第四,主动(转动)控制装置虽然能解决上述三方面问题,但是,存在意外能源切断控制***完全失效的风险。In summary, the structural vibration control system has an indispensable role, but the existing structural vibration control system has the following shortcomings: First, the translational TMD control device can only control the translational motion of the structure and affect the swing The control is invalid. Although the translational AMD control device can control the swing vibration, the control efficiency is extremely low and cannot meet the requirements of use; second, the passive moment of inertia tuned damper is effective for the control of the swing vibration movement, but it needs to be carried out for the structure itself Complicated frequency modulation has low control efficiency and poor effect on some complex structures. It has shortcomings such as low robustness, low controllability, and small application range; third, the control system has a small application range, limited control force output, and control The effect is limited, and the energy utilization rate of the control system cannot be guaranteed, which cannot meet the economic needs. Fourth, although the active (rotating) control device can solve the above three problems, there is a risk of the accidental energy cut-off control system completely failing.
本发明就是在这样的背景下产生的。The present invention was produced under this background.
